MIDSA - MIcroencapsulated Diets for Sustainable Aquaculture 2020

MIDSA - MIcroencapsulated Diets for Sustainable Aquaculture 2020

This proposal builds on a highly successful EIT Food project that began in 2019. We have developed a highly nutritious feed product for bivalves (mussels, clams, scallops and oysters), in the form of microencapsulated particles, and known as BioBullets. 

This feed promises to increase bivalve hatchery production rates through uplift in the quality of broodstock and higher survival and growth of juveniles. By using a powdered diet, there is no need for a hatchery to produce their own cultures of live feed (algae) which can be very expensive and unreliable. The nutrients that we put inside our artificial diets come from the ‘side streams' of existing aquaculture systems, making our super-food especially sustainable through a circular economy. During 2019 we demonstrated at the pilot scale that we can manufacture particles that are edible to oysters and mussels and which can result in positive growth. In this continuation project we plan to demonstrate full commercial scalability. This will involve

  1. a commercial production run of mussel larvae and broodstock to compare growth and survival with mussels fed on conventional diets;
  2. optimisation of feed concentrations to maximise growth and minimise wastage;
  3. commercial production of a reliable, standardised artificial diet;
  4. determination of optimal packaging and storage needs;
  5. full economic viability anlaysis;
  6. consumer panel testing to ensure acceptability to end-users.
